Wear of Ni3Al-based materials and its chromium-carbide reinforced composites

A number of laboratory studies have indicated that Ni3Al-based alloys have significant potential in wear-critical applications, especially in sliding wear in a temperature range between 400 and 650 °C. In this study, the wear behavior of an iron-alloyed Ni3Al with composition of Ni–18.8Al–10.7Fe–0.5Mn–0.5Ti–0.2B in atomic percentage and its composites reinforced by 6 vol.% Cr3C2-particles were investigated. Hot isostatic pressing (HIP) and...
